Fluid Regulation And Perfusion System Flashcards
1
Q
Transport routes in perfusion
A
▪️intercellular cleft-channel between 2 cells (brain)
▪️fenestration-pores (liver and kidney)
▪️endothelial cells
2
Q
Sympathetic nervous system- CVS
A
▪️innervates arteries, arterioles in most organs
▪️releases noradrenaline (NE) as a neurotransmitter
▪️causes vasoconstriction (except heart and brain)
3
Q
Neurotransmitter Receptors for CVS
A
▪️alpha 1-vasoconstriction
▪️beta 2- vasodilation (coronary vessel)
▪️beta 1- control SAN, AVN
4
Q
Parasympathetic nervous system- CVS
A
▪️innervates some arteries and arterioles
▪️realises ACh as a neurotransmitter
▪️causes dilation of vessels
